- 0.61: Nicola Salmoria added Wily Tower (Irem 1984) and clone Atomic Boy (Memetron license 1985). TODO: Unless there is some special logic related to NMI enable, the game doesn't rely on vblank for timing. It all seems to be controlled by the CPU clock. The NMI handler just handles the "Stop Mode" dipswitch. Flip screen (if it's like the other Irem games, the dipswitch has to be polled directly). Sound: it's difficult to guess how the I8039 is connected... there's also a OKI MSM80C39RS chip. One unknown ROM. Samples?

- 9th May 2002: Nicola Salmoria added the color PROMs to Wily Tower.

- 5th May 2002: Nicola Salmoria sent in a preliminary driver for Wily Tower / Atomic Boy but color PROMs are missing and sound isn't emulated.
